Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

We review the theoretical developments and conceptual advances that stemmed from the
generalization of QCD to the limit of a large number of color charges, originally proposed by't …

We consider examples of “hidden-valley” models, in which a new confining gauge group is
added to the standard model. Such models often arise in string constructions, and …

We show that it is possible to construct explicit models of electroweak symmetry breaking in
which the number of techniflavors needed to enter the conformal phase of the theory is small …

Quantum field theory is the basis of our modern description of physical phenomena at the
fundamental level. This systematic and comprehensive text emphasizes nonperturbative …

We investigate theories in which the technifermions in higher dimensional representations of
the technicolor gauge group dynamically break the electroweak symmetry of the standard …

We examine a double trace deformation of SU (N) Yang-Mills theory which, for large N and
large volume, is equivalent to unmodified Yang-Mills theory up to O (1/N 2) corrections. In …

We investigate new models of dynamical electroweak symmetry breaking resulting from the
condensation of fermions in higher representations of the technicolor group. These models …

We present a broad conceptual introduction to some new ideas in nonperturbative quantum
field theory (QFT) that have led to progress toward an understanding of quark confinement in …

Volume independence in large N c gauge theories may be viewed as a generalized orbifold
equivalence. The reduction to zero volume (or Eguchi-Kawai reduction) is a special case of …
